II ATE PATEN UFIQO WILLIAM LIONEL I-IEAP, OF GRAND HAVEN, MICHIGAN,ASSIGNOR TO WILLIAM HEAP & SONS, OF GRAND HAVEN, MICHIGAN, A FIRM.

CLOSET-FLUSHING- lvIECI-IANISM.

To all whom it may concern Be it known that I, WILLIAM LIONEL HEAP, acitizen of the United States of America, residing at Grand Haven, in thecounty of Ottawa and State of Michigan, have invented certain new anduseful Improvements in Closet-Flushing Mechanisms, of which thefollowing is a specification, reference being had therein to theaccompanying drawings.

The invention relates generally to a flushing mechanism for closets, andmore par ticularly to the control mechanism for the flushing valve, andit consists in the construction of the valve-actuating means, in thenovel arrangement and combination of parts, and in various details ofconstruction, all as will be more fully hereinafter described and moreparticularly pointed out in the claims.

In the drawings,-Figure 1 is a view in side elevation of a valve controlmechanism embodying my invention; Fig. 2 is a similar view, showing theparts in a difi'erent position; and Fig. 3 is a view in perspective ofthe parts of the controlling mechanism, detached.

For the purpose of illustration, I have shown and will describe a valvecontrolling mechanism of the type wherein a push or slide rod governsthe actuation of the valve, the button being arranged centrally of thetank above the seat and extending in right angular relation to theformer.

The reference-letter A designates the tank, of any suitableconstruction, and in this instance of the low-down type.

B is the push or slide rod, extending through a suitable opening, as a,in the front wall of the tank, and b is the usual push button.

C indicates the flushing valve seat, D the valve, and E a connectionpreferably in the form of a lift wire or rod-that serves vention toobtain a construction that will Specification of Letters Patent.

permit a maximum travel of the valve from its seat for flushing on aminimum travel or movement of the operating member, in whatever form itmay be, usually located on the exterior of the tank.

In the particular case here illustrated, wherein the operating member isin the form of a push rod, such a construction as referred to isparticularly advantageous, as owing to the short travel the rod isrequired to make it necessarily projects but a slight distance beyondthe tank.

To accomplish the desired result, I interpose between the push rod andthe lift wire, and suitably connect to each a multi-plying lever E,which on slight movement of the rod is designed to lift the valve amaximum distance from its seat, permitting the tank contents to bereadily and quickly discharged. Furthermore, by increasing the distancethrough which the operating force acts, as compared with the distancethrough which the weight or resisting force is moved, the operatingforce required to actuate the valve is decreased.

Within the tank interior opposite the opening a is positioned a bracketF, formed at its upper end with a pair of apertured depending ears 0,for securing the bracket to the wall of the tank; at its lower end withan arm (Z having an upturned apertured end 6; and intermediate the partsdescribed with a pair of spaced inwardly projecting ears f, providedwith hearing apertures f F. The lower portion of the bracket body isapertured, as at g, which registers with the opening in the upturnedportion 6, and these two openings constitute a double bearing for thepush rod B.

Positioned between the ears f, and pivoted upon a pin 9 engaging theapertures f, is a bell-crank lever G, which is preferably formed of twospaced similarly-shaped sections having lugs h, between which is pivoteda link I.

II is a yoke-shaped lever section, terminating at its forward end in asingle laterally projecting apertured portion 2', with which the liftwire or rod is connected, having the spaced ends thereof positioned uponopposite sides of the ears f, and pivoted for vertical swinging movementupon the projecting ends of a pin '5 engaging the bearing apertures J.The bell-crank lever is pivotally connected to the section H through themedium of the link I, which has a pivotal connection with a pin jcarried by ears 7L depending from the lever H, and also has a pivotalconnection with the push rod B, elongated openings 7' being formed inthe bell-crank, which receive a cross-pin 70 extending transverselythrough the rod, as shown.

As constructed, it will be obvious that upon slight inward movement ofthe push rod the flushing valve will be raised the usual distance fromits seat, and further that the extent of travel of the flushing valve islimited, so that there is no possibility of the valve being accidentallymoved out of operative relation to its seat. The stop that acts toregulate the throw of the valve is the upturned end sectione of thebracket, against which the lower end of the bell-crank strikes when thevalve is at the proper distance from its seat to permit proper flushing.

In cases where a relatively heavy valve is employed for controlling thedischarge of the tank contents, as for instance the usual glass float, Ideem it advisable to offset the weight of the valve, so as to permit ofmore easy operation of the controlling means. With the construction ofcontrol mechanism described, the counterweight is formed by means of ayoke J, the lower portion K of which is properly weighted and the armmembers apertured, as at Z, at their upper ends to engage studs m uponthe yoke section H of the multiplying lever.

By forming the bell crank and yokeshaped levers of spaced members, notonly is the strength of the lever mechanism in creased, but also thespaced bearings prevent the levers from twisting or bending sidewise,while the pivotal connection with the push rod is such as to prevent thebutton from rotating.

What I claim as my invention is,

1. In a closet flushing apparatus, the combination with a tank formedwith an opening in one of its walls, of a push rod located within theopening and projecting beyond the wall sides, a two-point bearing withinthe tank supporting the inwardly projecting portion of the rod, a flushvalve, and a lever connection between the valve and the rod secured tosaid rod intermediate the two points of said bearings.

2. In a closet flushing apparatus, the combination with a tank, a pushrod extending through the tank wall, a flush valve, a member within thetank having a portion spaced from the wall thereof supporting the rodand limiting the travel of the latter, and a lever connection betweenthe rod and the valve secured to the rod intermediate said member andsaid tank wall.

3. In closet flushing apparatus, the combination with the tank and theflushing valve, of a bracket secured to one wall of the tank, havingspaced bearings, a push rod extending through the tank wall and engagingsaid bearings, and a lever connection between said rod and valve, thepoint of connection with said rod being intermediate of said bearings.

4:. In closet flushing apparatus, the combination with the tank and theflushing valve, of a bracket secured to one wall of the tank, havingspaced bearings, a push rod extending through the tank wall and engagingsaid bearings, a lever connection between said rod and valve, and meansadapted to alternately engage said bearings, for limiting the travel ofsaid rod.

5. In closet flushing apparatus, the combination with the tank and theflushing valve, of a bracket secured to one wall of the tank, a push rodfor operating said valve, and a multiplying lever connecting said valvewith the push rod, including a bellcrank lever fulcrumed upon thebracket and connected to said rod.

7 In closet flushing apparatus, the combination with the tank and theflushing valve, of a bracket secured to one wall of the tank, a push rodfor operating the valve extending through the tank wall, and amultiplying lever connecting said valve with the push rod comprising anarm having onerend pivoted to the bracket and the other end connected tothe valve, a bell-crank lever pivoted in bearings upon the bracket, andhaving one end thereof connected to the push rod, and a link connectingthe other end of the bell-crank with said arm, and a counterweightsecured to the arm.

8. In closet flushing apparatus, the combination with the tank and theflushing valve, of a bracket secured to one wall of the tank, a push rodfor actuating said valve, and a multiplying lever connecting the rodwith the valve including a counter- Weighted arm pivotally secured tothe bracket and having its opposite end connected to the valve.
